I recently upgraded from vbox 2.0.4 to 2.1.2 on windows XP SP3

When I launch my vm's it just hangs now...in the machine log the last line is:

00:00:04.001 Guest Log: BIOS: Booting from Hard Disk...

and nothing else ever happens.

I've already uninstalled/reinstalled, even installed it on a new machine without any luck.

Any suggestions to debug/resolve this issue?

Ahmmm... downgrade to 2.04/6 and restore vdi from backup?

The downgraded version wouldn't open the files either. I went back to an old rar'd copy of the HD image and its working - I have unfortunately lost all the data I was working on.

Is there a HD image repair tool available anywhere?

Closed the vm, tried restarting it - now the image has been corrupted again...boot up hangs like before

Sounds more like a hardware/software host problem then a VM problem. Did you restore the VB config files as well? Try some diagnostic software on your host first to exclude problems there.

No I didn't restore any VB files.

What diagnostic software can you refer me to? The included help files and manual is not very helpful for troubleshooting this kind of problem.

DiskDirectorSuite10.0_d_en
hdtune_253
Heavyload
swissknife
Etc...

Are there any size limits on the virtual HD's? i.e. >4GB craps out?

To me it looks like a problem with vbox and I would like to find more detail on where its hanging up...

It looks like you are using FAT32 disks which has a 4g limit. Convert to ntfs.

Both host machine and vHD are NTFS

There is no reason why then, I have vdisks of many gigs large. Do you use harddisk compression?

No. It was just a shot in the dark. I was suspecting that the vHD image somehow got corrupted after adding contents to it.

i have the same issue, the vhd machine boot but after that i install vm addiction, the VM not go up (black screen)...

if i boot the same image from virtual pc the VM boot with chkdsk..
